Self-heating device thermal shock water entry accident scene simulation test device and test method

Abstract

The invention discloses a self-heating device thermal shock water entry accident scene simulation test device and test method, which can complete various test types such as a thermal shock test, a thermal shock water entry test, a seawater simulation test, a seabed long-term storage state environment adaptability assessment test, a seabed vibration environment adaptability assessment test and thelike. The experiment types can comprehensively simulate various accident environment loads of the self-heating device in launching and falling accident scenes, an analysis tool can be provided for product state response of the self-heating device from a dynamic scene to a deep sea storage scene, and technical support is provided for accident environment adaptability evaluation, improved design andthe like of products. The test piece launching device is used for simulating a scene when the test piece falls into seawater, can simulate the water entry angle of the test piece and can also simulate the water entry speed of the test piece, and compared with the traditional technology, the scene simulation is more real, and the detail consideration is richer.

Description

technical field [0001] The invention belongs to the technical field of self-heating devices, and in particular relates to a simulation test device and a test method for a scene of a thermal shock into water accident of a self-heating device. Background technique [0002] Self-heating devices, including space heat sources / power devices for deep space exploration such as isotope heat sources / power sources, have an important role in the field of space development due to their compact structure, high reliability, good radiation resistance, high mass specific energy, and low failure rate. The United States and the Soviet Union / Russia have applied self-heating devices to space missions many times. However, the application of radioactive materials in self-heating devices brings safety risks in accidents. [0003] Accidents have the following characteristics: [0004] 1. In the event of an accident, the product will fall at a certain height at a certain speed; [0005] 2....

AI Technical Summary

Problems solved by technology

[0006] 3. The product is a self-heating product, which is greatly different from seawater temperature, forming a temperature shock;

[0008] 5. If the product is difficult to salvage, it will be located on the seabed for a long time

[0015] 2. The load analysis of the thermal shock water entry accident scene is not in-depth

[0017] 3. The existing test process is not standardized

[0018] The current thermal shock water test carried out in various countries has not formed a unified standard, and there are no relevant standards, so it is impossible to standardize, guide and carry out the test

[0019] In general, since the application field of self-heating devices is at the forefront of science and technology, the analysis of product safety accidents in various countries, especially the research on the scene of thermal shock into water accidents is still in its infancy
